I don't even like MLP, I used to. I'm here because a brony friend invited me. I'm a nationalist, I also have friends online who are also nationalist and share the same interests as me (anime, music, video games.)
Honestly, there was a lot of garbage in the 80's. And you had boy bands pop out in the 90's. Actually 80% of what I listen to is post 1990 to modern day stuff. Mainly underground stuff but not exclusively.
